Used properly, ID scanning technology will catch both fake and expired ID documents. Good judgment and common sense on the part of the person scanning also helps to ensure that customers do not enter a bar with expired ID.
A good quality ID scanner may take the form of a separate scanning device, or it may come in the form of a mobile telephone application. Errors in scanning and failing to catch an expired ID are typically caused by human error, such as failing to adjust the date and time on the device properly. Best practices along with high-quality technology produce the best results in terms of catching expired IDs.
